-- restores backup automatically if any install step fails
-- restarts gateway during install, then validates `dirigentway/no-reply` is visible via `openclaw models list/status`
-- writes a change record for every install/uninstall:
-  - directory: `~/.openclaw/dirigent-install-records/`
-  - latest pointer: `~/.openclaw/dirigent-install-record-latest.json`
+- installs plugin + no-reply-api into `~/.openclaw/plugins`

+- supports `--no-reply-port` (also written into `plugins.entries.dirigent.config.noReplyPort`)
+- does not maintain install/uninstall record files
